VARIABLE VOLTAGE SYSTEM
Inductive electric equipment or subassemblies (coils or windings) are ideally tested at frequencies of more than 50 Hz. Thus, we have developed a system with variable voltage up to 2,500 V and variable frequencies up to 600 Hz that provides sinusoidal power (distortion factor of < 3 %) for resistive and inductive specimens. Depending on the design the test voltage is provided centrally on the IGBT inverter or by decentralized socket combinations. The test connection, the system activation, as well as the capture/storage of measured values, is carried out by a measuring unit.
